Two-year-old Logan Vanderkleed of Lafayette died in a hospital Thursday morning — a week after the accident.

Family members say Logan was sleeping in the car on Aug. 17, about 30 feet from where his father and grandfather were working on another car. His parents, Drew and Lisa Vanderkleed, say they believe he had woken up, stuck his head out of the window and accidentally rolled it up.

Logan's mother, Lisa Vanderkleed, more fully explained the situation in a post on her "Love for Logan" Facebook page writing: “During nap time, my hubby and his dad were cleaning a vehicle out right next to our vehicle that the kids were in, so since they could see the kids in the car right there and it was super hot outside, they left the kids in the car with the air running and windows up. Our son must have decided to put the window down to look for daddy or tell them something and then somehow rolled it up on himself (the window button on the explorer is a toggle switch so left and right makes it go up and down) which is unlike our other car window in which you actually have to pull up on the lever to move the window.”

Drew Vandkerkleed says he and his father attempted to resuscitate the boy and called 911. Logan had been without oxygen for several minutes and had no pulse.

Tippecanoe County Chief Deputy Steve Hartman says prosecutors are reviewing the case, which investigators have determined was an accident.
